Answer:
false
Step-by-step explanation:
A linear equation has x to the first power
or of the form x plus a constant
This has x to the fifth power so it is not linear
Area=legnth times width
width=2/3 legnth
w=2/3l
a=lw
subsitute
a=l(2/3l)
a=864
864=2/3l^2
multiply both sides by 3/2 to clear fraction
2592/2=l^2
1296=l^2
square root both sides
36=legnth
width=2/3 legnth
width=2/3 times 36
width=72/3=24
legnth =36 feet
width=24 feet
Answer:
9, 30, 27
Step-by-step explanation:
To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.
So, we must add the sides to get 66 feet.
n+3n+3+4n-9=66
Combine like terms, and solve:
(n+3n+4n)+(3+-9)=66
8n+-6=66
8n-6=66
n=9
So if n=9, we can easily find the value of the other sides.
3(9)+3=30 feet.
4(9)-9=27 feet
So, the sides are 9, 30, and 27 feet (in order).
Answer: Hello There!................
x=-3.5
Step-by-step explanation:
Mark me brainest please. Hope this helps. Anna ♥
Use the red dots as two points in the line.
Slope = change in y over the change in x.
point 1: (-5,4)
Point 2: (5,-2)
Slope = (-2 - 4) / ( 5 - -5)
Slope = -2/10
Slope = -1/5
